Frequently asked questions
What is a passphrase?
A passphrase is a sequence of random words, like "Maple-Otter-Canyon7-Frost". Six random words from a list of 1,000+ give about 60 bits of entropy while staying easy to type and remember.
Password or passphrase — which is better?
Both are strong when generated randomly. Random passwords are denser; passphrases are easier to remember and type, which makes them good for master passwords and device logins.
Is anything sent to a server?
No. Everything is generated locally in your browser with the Web Crypto API.
How strong is a passphrase?
A passphrase of five or six truly random words from a large word list is extremely hard to crack, while being much easier to remember and type than random characters.
What makes a password strong?
Length and randomness. A long password chosen randomly is far stronger than a short one with substitutions like “P@ssw0rd”, which attackers already try.
